The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 720 nm . A) What's the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope. B) For comparison, what is this distance as a multiple of the...
Name 1. A refracting telescope is built with a 44.0 cm diameter objective lens that has a 1.85 m focal length It is used with an eyepiece with an angular magnification of 14.0. (a) (5 pts) What is the local length of the eyepiece? (b) (5 pts) what is the angular magnification of the telescope? (c) (5 pts) What is the distance between the objective lens and the eyeplece? 2.

The objective lens of a certain refracting telescope has a diameter of 59.0 cm. The telescope is mounted in a satellite that orbits the Earth at an altitude of 335 km to view objects on the Earth's surface. Assuming an average wavelength of 500 nm, find the minimum distance between two objects on the ground if their images are to be resolved by this lens.
Which of the following are functions of the eyepiece lens of a refracting telescope? Check all that apply. A to produce an image whose angular size is greater than that of the object B to magnify the image produced by the objective lens C to reverse the orientation of the image produced by the objective lens D to form an image at the focal point of the objective lens What must result if the eyepiece lens of a refracting telescope...
The eyepiece of a refracting telescope has a focal length of 9.00 cm. The distance between objective and eyepiece is 1.8 m, and the final image is at infinity. What is the angular magnification of the telescope?
Can you design a refracting telescope using two convex lenses? What are the required conditions for such a telescope?

The Yerkes refracting telescope has a 1 m diameter objective lens of focal length 20 m. Assume it is used with an eyepiece of focal length 2.31 cm. Find the angular magnification of the planet Mars as seen through this telescope.
A reflecting telescope has a main mirror with fM = 470 mm. If an eyepiece with a magnification of 15 is used, what is the total magnification of the telescope? Assume the near-point distance of the eye is 25 cm.
A refracting telescope is used to view the Moon (diameter 3480 km, distance from Earth 385,000 km). The focal lengths of the objective and eyepiece are +2.45 m and +16.1 cm, respectively. (a) What should be the distance between the lenses? m (b) What is the diameter of the image produced by the objective? cm (c) What is the angular magnification?
